Abstract

The invention relates to wheat seeders in agricultural machinery, and discloses a non-tillage wheat seeder with an adjustable straw mulching quantity for full-straw mulched lands. The non-tillage wheat seeder is characterized in that a rotary arbor (7) of a straw smashing cleaning machine is connected with a power output shaft of a tractor, and a transverse auger (2) is arranged behind straw smashing cutters; adjusting gaps are transversely formed in an upper cover face plate (7a) among the straw smashing cutters and the transverse auger (2), an adjusting seat strip (1a) is fixed to a side of each adjusting gap, and rectangular adjusting plates (1) are inserted into the adjusting gaps and are fixed onto the adjusting seat strips (1a) by the aid of bolts; a plurality of screw holes are formed in the adjusting plates (1), and the bolts are connected with the screw holes in different positions, so that the insertion depths of the adjusting plates (1) can be changed, smashed straw which is fed into the transverse auger (2) can be stopped, and the quantity of the smashed straw can be adjusted; fans are configured at an output end of the transverse auger (2), the straw can be rearwards conveyed to the upper side of a wheat fertilization seeder (4) via a pipeline (3), and the wheat fertilization seeder (4) is configured behind the transverse auger (2). The non-tillage wheat seeder has the advantages that a proportion of the quantity of straw returning to fields to the mulching quantity can be changed, and problems in the aspects such as completely returning straw to fields or completely mulching the straw on lands can be solved.

Description

A kind of adjustable full straw covering plot no-tillage wheat sower of straw amount that covers
Technical field
The present invention relates to the sower in agricultural machinery, specifically relate to the improvement mechanism of the Work machine of stubble corn before being applicable to, paddy rice, the rear no-tillage seeding wheat of cotton crop results.
Background technology
China's corn-wheat, paddy rice-wheat, cotton-wheat crop rotation district, after preceding crop corn, paddy rice, cotton harvesting, need sowing in time wheat, because field after mechanized harvest has retained a large amount of corns, paddy rice, cotton stalk, bring larger difficulty to lower batch of wheat Mechanization sowing.
The patent No. discloses 201210397462.2 " a kind of broken straw, clear straw, fertilising, sow, cover the multi-functional unit of straw ", sow during for the large crop of the stalk amounts such as corn, paddy rice at front stubble, cover the straw of pulverizing, solve the defect of prior art, but when the front stubble of the no-tillage seeding crop that to be the stalk amounts such as corn, paddy rice large, as stalk all covers, or all and field exists following problem:
1, stalk all also behind field Nitrogen In Soils element not enough, make microorganism and crop contention nitrogen, result stalk decomposes slow, wheat seeding because of nitrogen stress yellow, seedling a little less than, undergrowth; Make soil become too loose, macrovoid is too much, causes running the wind loss of moisture, affect seed sprouting grow, make wheat take root the not firm root that occurs hanging.
2, stalk cover blocked up easily cause early stage low temperature on the low side, affect the supply of nutrient; Low or while not applying fertilizer, growth of seedling is not good enough in fertility, a little less than causing seedling Huang, seedling, seedling is grown and postpone even dead seedling.
Wish a technical scheme behave that can overcome above deficiency for above problem this area.
Summary of the invention
The object of the invention is to for above-mentioned the deficiencies in the prior art, provide a kind of and can regulate the full straw covering plot no-tillage wheat seeding machinery that covers straw amount, realize full straw covering plot no-tillage farming and cover the adjustable part flow arrangement of straw amount, realize part straw-returning, the covering of part stalk, and crop-residue incorporation and the adjustable device of overlay capacity ratio.
Object of the present invention is realized by following technical scheme.
Cover the adjustable full straw covering plot no-tillage wheat sower of straw amount, it is characterized in that: certainly go to rear following configuration:
The swivel knife shaft that is connected the horizontal wide cut box-type crushed stalk clear straw machine vertical with direction of travel by tractor motive power output shaft configures many broken straw cuttves on cutter shaft, and the rear of broken straw cutter is a horizontal screw feeder;
On the upper encloser panel between broken straw cutter and horizontal screw feeder, laterally offer and regulate seam, regulating seam one side secured adjusted seat bar, regulating the adjustable plate that inserts rectangle in seam, by bolt, adjustable plate is fixed on adjustment seat bar;
The straw that adjustable plate has stopped the broken straw cutter pulverizing of part enters horizontal screw feeder;
On adjustable plate, offer multiple screws, bolt connects the screw of diverse location, can change the degree of depth of adjustable plate insertion upper encloser panel, the amount that regulates the straw that stops pulverizing to enter horizontal screw feeder;
The output configuration blower fan of horizontal screw feeder, delivers to wheat fertilizing sower top by the road backward, and the stalk scope of shedding out is suitable with wheat fertilizing sower width on width;
At the rear of described horizontal screw feeder configuration wheat fertilizing sower.
Adopt the technical program, on the upper encloser panel between broken straw cutter and horizontal screw feeder, laterally offer and regulate seam, regulating seam one side secured adjusted seat bar, regulating the adjustable plate that inserts rectangle in seam, by bolt, adjustable plate is fixed on adjustment seat bar; The straw that adjustable plate has stopped the broken straw cutter pulverizing of part enters horizontal screw feeder, regulates thus part straw-returning, part stalk to cover, and reaches the object that can change crop-residue incorporation and overlay capacity ratio.
Further, described one regulates seam to be divided into some sections, and adjustable plate is corresponding some.
Further, described adjustment seat bar is flanging angle steel, and a side is fixed on upper encloser panel, and opposite side is offered screw.
Beneficial effect of the present invention, pass through technique scheme, adjustable plate has stopped part straw and has entered horizontal screw feeder, part straw directly returning to field, part stalk covers by screw feeder and pipeline, can change crop-residue incorporation and overlay capacity ratio, overcome as all also fields or all problem of covering existence of stalk.The technical program is simple in structure, and cost is low, and assembling is simple, reliable, and effect is remarkable.
